In l igs. 1 and 12 of the drawings, the forward end of the machine has been indicated by the reference character A, the

rear end of the'-. machin.e being, indicated by the reference character B. Y in putting theZpresimtinvention into practice, two parallel lines of .supports 1 are provided, the lines-of supports 1 upholding, respectively, longitudinz'il I-beams 2 connected by cross braces 3. The foreoingwv'ill found to'be a secure and satisfactory foundation for the working parts of the structure, but, obviously, any 'suitable foundation maybe provided.

Erected on one of the I-beanis 2 is a series of standards denoted by the numerals 4, (1,7, 8, 9 and 10. I-beain 2 isa series otstandards denoted .by the numerals 11. 1 .2, 15,16, 17 and 1S. Noting Fig, 1'1 which depicts many ficounnozi 'teatu es of all of the standards, it sis tohe observed that the standards are rovided with guide slots 19. in the standards adjacent their upper ends, transverse notches 20 are formed, the notches 30 re- Erected on the other ceiving thrust plates 21 into which are threaded screws 22 controlling the movement ofbearings 23, grooved as indicated at 24 to cotiperate with the standards. The bearings 23 are provided with openings 25.

The bearings 23 in each standard form supand 14 carry an upper shaft 28. An upper shaft 29 coacts with the standards 7 and 15. The standards 8- and' 16 carry an upper shaft 30 and an upper shaft 31 is carried by the standards 9 and 17. The standards 10 and 18 carry an upper shaft 32.

As shown in Fig. 1, the several pairs of standards carryglower shafts 33, 34, 35, 36, 37, 38 and 39. The upper shafts 26, 27, 28, 29, 30, 31 and 32 carry gear wheels 40 meshing into gear wheels 41, carried by the lower shafts 33, 34, 35, 36, 37, 38 and 39. T he gear wheels 41 on the respective lower shafts are connected with each other by means of idle pinions 42 mounted on shafts 43 carried'by lugs 44 forming parts ofthe standards 11, 12, 14, 15, 16 and 17.

Noting Fig. 12 and comparing the same with Figs. 21 to 27 both inclusive, the upper shafts 26, 27, 28, 29, 30, 31 and 32 carry, re spectively, rollers 45, 46, 47, 48, 49, 50 and 51. The lower shafts 33, 34, 35, 36, 37, 38 and 39 carry, respectively, rollers 52, 53, 54, 55, 56, 57 and 58, the rollers upon the upper and lower shafts being adapted to coiiperate in pairs as clearly shown in Figs. 21 and 27 of the drawings.

The roller 52 is provided with a groove 59, the Walls 60 of which flare as they extend outwardly. On the roller 45 and cooperating with the groove 59 is a rib 61 shaped to conform to the groove. In the roller 53 there is a groove 62, the walls 63 of which are inclined with respect to the base of the groove. The walls 63 of the groove 62, however, slant more abruptly with respect to thebase of the groove than do the walls 60 of the groove 59. On the roller 46 there is a rib 64 shaped to fit in the groove,62. The groove 65 in the roller 54 is of rectangular transverse section, the walis 66 thereof being parallel to each other. A 3?;- 67 on the roller 47 fits into the groove 65 and is of rectangular form. The groove 68 in the roiler of rectangular cross section. The rib 70 on the roller 48 projects into the groove 68, the edge of. the rib 70 being beveled shown at 69. The groove 71 in the roller 56 is of rectangular form and one edge 72 of the rib 73 on the roller 49 is beveled ofi". The edge 72 approaches more nearly to parallelism with the base of the groove 71 than does the edge 69 in Fig. 24. The base of the groove in the roller 57 slants as shown at 74, and the edge 75 of the rib 76 on the roller 50 slants in an opposite direction, that is, the rib 76 and the grooved portion 74 of the roller 57 are in the form of the truncated cones, the smaller ends of which point in opposite directions In the case of the roller 58, the slanting face of the groove is shown at 77 and the rib on the roller 51 is shaped accordingly as shown at 78. The parts 77 and 78 in Fig. 27 define a more acute angle with respect to the axes of the respective rollers than do the corresponding parts in Fig. 26.

Referring to Figs. 2 to 8 both inclusive and noting particularly Fig. 2, it will be ob served that upon one or both edges of the sheet there is formed a trough 79 the walls 80 and 81 of which converge, the body portion of the sheet being indicated at 83 and the numeral 82 indicating the base of the trough 79. The bead is of the form shown in Fig. 2- afterthe sheet has passed by the first set of rollers, that is, by the rollers 45 and 52. The part 82 extends approximately parallel to the part 83. By means of the rollers 46 and 53, 'the bead is then shaped as shown in Fig. 3. The base 84 of the bead remains parallel to the body 83, but the walls 85 and 86 are brought more nearly into parallelism with each other. Fig. 4 shows the head after the same has been operated on by the rollers 47 and 54. The base 87 of the bead remains parallel to the body portion 83 of the sheet, the walls 88 and 89 being brought into parallelism. The rollers 48 and 55 dispose the parts as shown in Fig. 5. The base 90 of the head is still parallel to the body portion 83 of the sheet, but the lip 01" wall 92 has been pressed inwardly at its free edge, toward the wall 91, this operationhaving been brought about by the part 69 in Fig. 24. Fig. 6 shows the bead as the same appears after the material has been operated on by the rollers 49 and 56 of Fig. The parts and 93 stand at right angles to each other, but

"the lip 94 has now been bent over so that it overhangs the part 93 to a markedand perceptible extent. The material then passes between the rollers 50 and 57 of Fig. 26, the coiiperating parts 75 and 74 serving to spring the base 96 outwardly, as shown in Fig. 7, and, to compact the lip 98 on the base 96. These parts now define an acute angle with respect to the portion 97 of the bead. By the coaction between the parts 78 and 77 of Fig. 27, the elements 99'and 101 of Fig. 8 have been bent-still further so that they define a more acute angle with respect to the wall 100.

The operation of the structure has been dealt with step-by-sftep hereinbefore, but briefly considered is as follows :-The sheet to be beaded and corrugated is passed between the various rollers shown in Figs. 21 to 27 both inclusive, and by this operation, the bead is disposed substantially in the condition shown in Fig. 8. Then the bead is bent laterally'until it stands at right angles to the body portion of the sheet, as shown in Fig. 9. This operation is brought about through the medium of the horizontal'wheels 104 on the platform 103. Then, the sheet of material passes between the corrugated rollers 115 and 116 and is finished ofl substantially as shown in Fig. 11 of the drawings. The sheet then passes between the guiding rollers 131 and 137 and is bent approximately into the curvature which it is desired that it shall assume.

Having thus described-the invention, what is claimed is 1. In a machine for shaping and bending sheets, a supporting structure having a guide; a first eccentric journaled on the supporting structure adjacent one end of the guide; a first bearing slidable in the guide at said end of the guide; a second bearing slidable in the guide at the other end of the guide; oppositely extended arms provided at their outer ends with straps, the strap of one arm coacting with the first eccentric; a second eccentric coacting with the strap ofthe other arm; a second shaft carried by the second eccentric and journaled in the second bearing; a first shaft forming a pivotal connection between the inner ends of the arms and journaled in the first bearing; means for operating the eccentrics individually; and cooperating sheet guiding elements carried by the shafts.

2. In a machine for beading sheets, a supporting structure including a substantially horizontal platform; a bead roller mounted for rotation in a plane parallel to the platform; a pair of superposed corrugating rollers journaled on the supporting structure to the rear of the bead roller; :1 pair of bending rollers disposed to the rear of the corrugating rollersz; means for moving the bending rollers together transversely of the line of advance of the stock, and for moving one bending roller toward and away from the other bending roller transversely of the line of advance of the stock; a retaining roller disposed between thecorrugating rollers and the bead roller and constituting means for holding the stock on the platform while the stock is passing to the corrugating rollers, the platform having a bead-receiving groove located near the periphery of the beading roller, the retaining roller, the corrugating rollers and the bending rollers being providd with bead receiving grooves located in alinement with the groove of the platform; and means for partially completing a bead in a sheet and for advancing the sheet to cause the partially finished sheet to coact with the bead roller.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
